Compressibility characteristics of compacted clay treated with cement, peat ash and silica sand

This paper investigates the compressibility characteristics of compacted clay treated with cement, peat ash and silica sand. For this purpose, one dimensional consolidation tests were conducted to determine the soil consolidation properties. The test specimens were trimmed from the compaction test s...

For this purpose, one dimensional consolidation tests were conducted to determine the soil consolidation properties. The test specimens were trimmed from the compaction test specimen.

It was concluded that, the compression settlement of the stabilized soil with the binder composition of 18% cement, 2% peat ash and 5% silica sand improved by almost 1.3-fold.
